Micro-milling can be used to create 2.5D features with a laser ablation. With the appropriate choice of process conditions surface roughness below 1 micron can be obtained.
Laser micro-milling is ideal for a wide variety of applications including:
- Production of micro-moulds
- Production of micro-stamping tools
- Creating microfluidics devices
How it Works
Laser Micro Milling is simple in concept. Each laser pulse ablates a very small amount of material. The laser is scanned across the surface to produce the desired feature. The number of pulses at each position determines the depth of the feature.
In practice the quality of the result is strongly dependent on the choice of laser and the scanning strategy adopted. In many cases the morphology of the starting material is also important with fine grained or amorphous materials producing the best results.
Oxford Lasers has many years of experience in carrying out complicated laser micromachining processes to laser mill fine features in a wide range of materials.
